It was over a year ago so my recollection could be faulty but the way I recall it was that they decided it was too difficult to build (different products with different T&C etc) and give the user experience they wanted. They then carried out an exercise to justify introducing bundles (including the infamous “5 person controversy”)- which then had to amended as they weren’t popular.
What I was thinking of is (Monzo Plus – you asked us to make it simpler, so we’ve created bundles - #237 by benjiportwin) and related posts of which there were many over a very long period…
We launched Plus with full customisation, so you could pick features individually. We learnt this was a mistake because it added too much complexity.
When we ran user testing to gather feedback on Monzo Plus, many users found it confusing and overwhelming. Our team had to step in to clarify what was going on at several stages, meaning that the product and its design weren’t clear enough.
They launched Plus first and then decided it wasn’t what they wanted to do
